During the process of silage corn, should take into consideration some aspects that will result in better utilization. The aim of this study was to evaluate the degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and starch digestibility and in vitro dry matter (DM) of silage corn hybrids due two textures, three stages of harvest, three particle sizes and processing by crushing. After harvesting and chipping, part of the material was crushed and then ensiled and sealed for 45 days. After opening the silos, analyzed the degradability in the incubation time of 20 hours using the technique in situ macro bag. The experimental design was a randomized split plot. The DM degradability was influenced only by the effect of stages of sampling used. The degradability of CP showed interaction between processing and particle size (Tp), noting that increased degradation due to processing. For NDF degradation significant interaction of factors, hybrid and processing, similar to the degradation of starch. The IVDMD was influenced by the effects of hybrid, stadium, Tp and processing. It can be concluded that benefits were higher with the use of processing associated with more advanced stages of harvest, in larger particle sizes.

Mouthwashes are used as an adjunct to tooth brushing for improving breath and preventing oral diseases. The aim of this study was to compare the in vitro Maximum Inhibitory Dilution (MID) of 3 mouthwashes with different active ingredients against mutans streptococci (MS). The products analyzed were PeriogardR, CepacolR and PlaxR Fresh Mint. Their antibacterial activity was assessed in duplicate in 96-well microtiter plates against 36 clinical isolates of MS. Each mouthwash was submitted to a serial two-fold dilution (1/2.5 to 1/5120) using double concentration of Tryptose Soy Broth with 1.0% yeast extract. The final volume in each well was 100 mL plus 5 mL of a bacterial suspension, equivalent to 107 CFU/mL. They were incubated microaerobically at 37oC for 48 hours and the MIDs determined. MID was 1/320 for PeriogardR and CepacolR, and 1/20 for PlaxR. Statistical analysis revealed that the MID of PeriogardR MID did not differ from that of CepacolR (p>0.05), and was higher than that of PlaxR (p<0.05). In conclusion, the antiseptic mouthwashes containing chlorhexidine (PeriogardR) and cetylpyridinium chloride (CepacolR) had higher in vitroantibacterial activity (MID) against MS than the antiseptic mouthwash containing triclosan (PlaxR), according to microbiological method employed.
